Abstract
The invention belongs to casting and forming field, specifically a kind of nodular cast iron crankshaft connected with auxilliary crankshuft model, its architectural feature is that bent axle apperance one end is connected with a secondary crankshaft apperance through the taper type connector, secondary crankshaft Via between centers ground connection is utilized riser feeding.The present invention has increased the quantity of bent axle under the situation that does not increase rising head, running channel, and the disjunctor bent axle of cast molding also is easy to clear up split, casting yield rate height.
Description
The invention belongs to the casting and molding field, specifically a kind of nodular cast iron crankshaft connected with auxilliary crankshuft model.
Existing ductile iron crankshaft model, its structure is generally and is provided with interconnective bent axle apperance, sprue, cross gate, slag trap, ingate and rising head successively on template, each bent axle apperance all directly links to each other with rising head, after moulding, the cast, each bent axle directly utilizes rising head to carry out feeding, adopt this model moulding to have a large amount of sand mold wedge angles, cause the bent axle burning into sand, percent defective is very high, this model arranged direction is complicated chaotic, is difficult to accurate installation, and the mould shift percent defective is very high, when cast blank, the molten iron utilization rate is low in addition.
The objective of the invention is to overcome the shortcoming of above-mentioned technology, a kind of production efficiency height, the low nodular cast iron crankshaft connected with auxilliary crankshuft model of casting percent defective are provided.
Feature of the present invention is: bent axle apperance one end is connected with a secondary crankshaft apperance through the taper type connector on same axis.
When the present invention produced crank shaft blank in casting, production efficiency height, percent defective were low.
The present invention is described in detail by embodiment below in conjunction with accompanying drawing.
Fig. 1, for the structure of nodular cast iron crankshaft connected with auxilliary crankshuft model cope match plate of the present invention show between figure.
Shown in Figure 1, secondary crankshaft apperance 2 connects together through truncated cone connector 3 and bent axle apperance 4 on template 1, making as a whole and bent axle apperance 7 is connected on the rising head 5 jointly, bent axle apperance 4,7 directly utilizes rising head 5 to come feeding, and secondary crankshaft apperance 2 then utilizes rising head 5 to carry out feeding by truncated cone connector 3 and bent axle apperance 4 indirectly.Rising head 5 links to each other with sprue 10 with ingate 6, slag trap 8, cross gate 9 on template 1, and when cast, molten iron enters in the die cavity of bent axle apperance 4,7 and secondary crankshaft apperance 2 by sprue 10, cross gate 9, slag trap 8, ingate 6 and rising head 5.On the symmetric position of bent axle apperance 4,7, secondary crankshaft apperance 2, be provided with other three bent axle apperances, be provided with six bent axle apperances on the whole like this template 1 altogether, six shared two rising heads 5 of bent axle apperance.Under the constant situation of running channel and rising head quantity, increased the quantity of bent axle apperance, in addition, secondary crankshaft apperance 2 and bent axle apperance 4 are convenient to the cleaning split of two disjunctor bent axles.
Template is corresponding with cope match plate under the present invention, thereby has formed spheroidal graphite cast-iron disjunctor mould jointly.
Claims (1)
1, a kind of nodular cast iron crankshaft connected with auxilliary crankshuft model is made up of template, bent axle apperance, sprue, cross gate, slag trap, ingate and rising head, it is characterized in that bent axle apperance one end links to each other with the secondary crankshaft apperance through the taper type connector on same axis.
